Sine and Cosine: Derivative
![[d/dx]](../../../d-dx.gif) (sin(x)) = cos(x)
- Alternate notation
- sin'(u) = cos(u)u'
- D(sin(u)) = cos(u)D(u)
- dsin(u) = cos(x)du
(cos(x)) = -sin(x)
- Alternate notation
- cos'(u) = -sin(u)u'
- D(cos(u)) = -sin(u)D(u)
- dcos(u) = -sin(x)du
See the derivation of this.
